try
convert image.gif -transparent white result.gif (or use result.png)
or if not perfectly white, then try
convert image.gif -fuzz XX% -transparent white result.gif
where the smaller the %, the closer to true white or conversely, the larger the %, the more variation from white is allowed to become transparent.
